MACHINE FOR FORNIING SAFE-PLATES.

Specification of Letters Patent.

Patented June 26, 1906.

Application filed February 27, 1906. Serial No. 303,256.

To all whom it may concern.- Be it known that we, JACOB BAUM, residlng at Cincinnati, in the county of Hamilton,

and FREDERICK J. NUTTING, residing at Day ton, in the county of Montgomery, State of Ohio, citizens of the United States, have invented certain new and useful Improvements in Machines for Forming SafePlates, of which the following is a specification.

Our inventionrelates to metal-forming devices, the object being to form of and in one continuous piece an angle-plate that may be used to form a side of a fireproof safe.

Our invention consists of a platen, a rollframe, rolls journaled in said roll-frame, and of means for reciprocating said roll-frame whereby said rolls are brought past said platen.

Our invention also consists of the parts and of the construction, combination, and arrangement of said parts, as herein fully set forth and claimed.

In the drawings, which serve to illustrate the construction and operation of our invention, Figure `1 is a plan and partial horizontal section on the line w of Fig. 2. Fig. 2 is an elevation of our improved machine, showing how the plate is held upon the platen preparatory to forming. Fig. 3 is a similar elevation showing the positions of the various parts of our improved'machine when the rollers have finished forming the angle-plate. Fig. 4 is a vertical section on the line a; of Fig. 3. Fig. 5 is a partial elevation of our invention, showing the positions of the parts when the machine has completed its cycle of operations, showing how the formed plate may be removed and another plate inserted.

Fig. 6 is a perspective view of part of the rollframe, rolls, and platen from below, showing how the excess metal is removed from the plate. Fig. 7 is a perspective view of the formed plate. Fig. 8 shows how said plate is applied to a safe.

Ve prefer to construct our improved machine as follows:

A bed-plate 1 supports the upright standards 2 and 3, which are provided with guideways 4 and 5, and a slide 6 has guides 7 and 8 engaging therein. The bed-plate 1 also has the rectangular guideway 9, in which the shank 10 of the platen 11 is adapted to slide upward and downward. Attached to the slide 6, preferably by bolts 12, is the .rollframe 13, in which are `journaled the rolls 14, 14, 15, and 15 at right angles to each other. The rolls 14 and -14 are plain cylinders, but the rolls 15 and 15 have the flanges 16 of such shape that when the roll-frame isforced downward the plate 17, resting upon the platen 11, has its sides bent downward over the edges of the platen, and the excess metal in the corners is squeezed downward, as at 18 in Fig. 6, and cut off between the blade 19 and the roll-flange 16. All the -rolls have journals 20.

For causing the reciprocation of the slide 6 and its attached roll-frame 13, as wellas to operate the various accessories thereto, we provide the main shaft-21, journaled at 22 and 23 in the standards 2 and 3, respectively, and at 24 and 25 in the brackets 26 and 27, attached to the standards 2 and 3, respectively. The slide 6 has upwardly-extending arms 28 and 29, slotted at 30 and 31, respectively, to pass over `the shaft 21, and the shaft 21 has the cams 32 and 33 rigidly mounted thereon adjacent the arms 28 and 29, respectively, which engage'therollers 34V on the respective arms. The roll-frame 13 and the slide 6 are apertured above the platen 11 to admit the clamp 35, having guides 36 and 37, engaging within guideways 38 and 39 in the arms 28 and 29, respectively. For the purpose of pressing this clamp downward and holding it down for vthe required period of time cams 40 and 41 are rigidly mounted upon the shaft 21 and engage rollers 42 upon the arm 43 of the clamp 35. The arm 43 is also slotted at 44 to pass over the shaft 21. For reciprocating the platen 11 the wedgebars 45 and 46 are mounted to slide laterally through the standards 2 and 3 andbe limited to horizontal movement only, while their in clined surfaces 47 and 48 engage vwithin the recess 49 in the shank -10 of the platen 11. For the purpose of reciprocating said wedgebars cams 50and 51 are rigidly mounted upon the shaft 21 within the brackets 24 and 25, respectively, and levers 52 and 53 are fulcrumed in the brackets 54 and 55, respectively. The levers 52 and 53 are slotted at 56 and 57, respectively, to receive the pins 58 and 59, respectively, which-are IOO inserted into the wedge-bars, and they also have studs 60 and 61, respectively, to engage the cams 50 and 51, respectively. The strippers 62 and 63 are also mounted to slide through guideways in the standards 2 and 3, are reinforced by the pedestals 64 and 65, and are likewise reciprocated by means of the levers 66 and 67 fulcrumed .in the brackets 54 and 55, respectively, and having the slidable studs 68 and 69 engaging the cams 50 and 51, respectively.

The various cams 32 and 33, 4() and 41, and 50 and 51 are so shaped and proportioned vthat when the shaft 21 is rotated in the direction of the arrow (shown in Fig. 4) the clamp l35 will press against the plate 17 upon the platen 11 and hold it there, whereupon the roll-frame 13 will be brought into motion, passing the rollers 14, 14, 15, and 15 downward past the platen 11 and forming the sides of the plate 17 at right angles to its body portion. When this has been completed, the roll-frame will begin to rise, and the strippers 62 and 63 will move inward until their ends are under the edges of the plate 17, Where they will be held while the platen, now brought into motion by the wedge-bars, is drawn downward and out of the formed plate, which will rest upon the strippers 62 and 63 until removed to admit of the insertion of the next plate to be formed. This will be inserted, as shown in Fig. 5, when the above cycle of operations will be repeated.

Suitable means, as the pulley 70, pinion 71,

and gear 72, are provided for rotating the shaft 21, and a clutch 73 of suitable construction is provided for the purpose of limiting said shaft to a single revolution. This clutch may be released by depressing either of the treadles 74 or 75, to which it is operatively connected by means of the rod 76. As will be seen, the plates may be inserted from either side of the machine or removed therefrom with the greatest convenience, all that is necessary being to heat the plate to redness, place it in the machine in proper position, and start the machine, which in a single revolution will form the angles complete and remove the excess metal. The corners of the platen 11 are rounded, as shown at 7 7 and the flanges on the rollers 1 5 and 15 are illeted, so that the corners .on the formed plate will be rounded at every point, while at the same time being slightly curved to form a nearly sharp angle, thus avoiding the crystallization and consequent weakening of the metal at the corners that results when they are formed square as well as improving the appearance of the inished prod uct. The size of the blades 19 may be varied to adapt them for removing the excess metal, so that when the plate is removed from the machine its edges will be true and require little or no work thereafter.

By forming and cutting the plates as above described, all blacksmith-work is obviated, while the properties of the metal will not be changed, since it is unnecessary to heat it excessively, asis necessary when welding is done. When the plate is removed from the machine, it appears as shown in Fig. 7 and is suitable :for forming the back of a safe without further manipulation. For the front of the safe the door-plates are cut out with suitable dies and the hinges attached, as shown in Fig. 8.

For forming plates of different size the platen 11, roll-frame 1,3, and strippers 62 and 63 may be remove-df and a'roll-frame and platen of suitable size yand strippers of suitable length inserted, these parts being made detachable and interchangeable for that purpose. The tie-rods 73'are'provided to properly brace the standards 2 and 3, as shown.

While we have shownfand described a peculiar construction herein, 4we do not wish to be understood as limiting ourselvesto it, but desire to make such changes as do not depart from the scope and spirit of our invention.
